TO ALL WHOM IT MAY CONCERN:

Be it known that L'CORNELIUS H. LATHAM, of Randolph, Cattaraugus county, and State of New York, have invented certain new and useful improvements in Tube Wells; and I' do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a section of the upper portion of my improved tube well, andv pump attached thereto.

Figure 2 is a horizontal section ofthe same.

Figure 3 is a section ofthe lower portion ofthe driving-pipe and driving-point.

Figure 4 is a horizontal section ofthe same.

This invention relates to the construction of pumps for pumping water to the surface by means of combining and using a wooden or stoneware tube or casing, of larger bore or diameter for the upper section of the well, in which the Yvalves and pump-barrel are located at a considerable depth below the surface o f the ground, with a driving-tube of smaller bore, which penetrates the water veins, and forms the lower section of the well; and it consists, first, in the construction and application of a combined coupling and valve-box seat, as a means of connecting the driving-tube to the pump-barrel; second, in connecting'and securely fastening a cast-iron driving-point, having a stem,iwhich enters the driving-tube by means of a wrought-iron band shrunk around the tube and over the stem.

Letters of like name and kind refer to like parts in each of the figures.

A represents the driving-tube, the lower end of which is slotted in a common manner for the. ingress of the water in the bottom of the well, as shown at a. B represents a cast-iron driving-point having a shank, b', projecting upwardly therefrom. This drivingpoint I connect to the lower end of the pipe as follows: The shank b is made ofthe same size as the bore of the tube, andis driven into the same while the tube is hot. Then I take a wrought-iron band, C, and shrink yit around the pipe and shank immediately above the shoulder of the point B. By this means a cheap driving-,point may be securely and firmly connected to the end of a driving-pipe, and made part thereof, so that when the pipe is for any reason drawn from the well, the joint will always be taken with it, instead of being left in the well, as is often the case with the driving-points now in use, and connected in a common manner. The ring of the band C further prevents the pipe from splitting, which it is liable-to while being driven into the ground with the required force. D Drepresent sections of stonewae'or wnooden tubing, each section having a projecting rim at each end. These `sections are connected together by means of the bolts d passing through the contiguous rims or flanges, forming a continuous tubo which composes the upper section of the well, and in which the pump-barrel is found. It is made water-tight by interposing strips of packing between the connected rims. The driving-pipe is connected to the lower end of the'lowest section of stoneware or wooden tubing by means of a cast-iron coupling, E. This is ancombined coupling and valve-box seat. The driving-tube screws into the lower end, which is small and tubular to receive it, while the upper part is enlarged, forming a iiange for connecting with the larger upper section forming the pump-barrel. This is bolted to the ange of the pump-barrel section D, and is provided with packing, so as to make thejoint water-tight. The lower valve is shown at F. The valve-box is shown at F; it is placed in a recess formed in the coupling E,-and is provided with abail f2, by which means it may' be lifted up, and cleaned of sand or other obstructions and then replaced,obviating the necessity of drawing all the tubing when the valve is clogged by any means, or out of order. The upper valve G works on that part of the stoneware or wooden tubing which forms more properly. the pump-barrel, as shown in the drawings, being attached toa long pump-rod, g', for that purpose. H represents the housing of the pump pla-ced above the surface,and H the lever or handle. The driving-tube A is made in sectionsof about teu feet in length, more or less, in a common manner, and these sections are screwed together as they are driven into the ground. The lower section containing the slits for the ingress of the water, and the driving-point, is 'first driven into the ground its length, and then another section screwed on and the driving-point continued until that has penetrated the ground its.length, and then another section screwed on and driven as before, and so on untilfthe .water veins are reached. Now suppose 1water is obtained at the depth of forty feet: I exeavate'"the ground aioundfthe driven pipe to the depth often or twelve feet, more or less, as the case may require, making a holel ofsuieient size to permit n man to work therein, and to Well up or curb, if necessary, and then remove the section or scctions ofthe driven pipe to that depth, and then connect the upper sections of the stoneware or wooden tubing D to the 'below section of the driven tube by ineens of` the cast-iron coupling E. The pump-barrel proper is in the lower section of the stoneware or wooden tubing, and lin-s the lifting-valve located therein, at u, considerable depth below the surface of the ground, :rnd below the reach ofthe frost.v The pump can now be easily worked; the section acting to the depth of twenty-five or thirty feet, as the cosemey be, and the lifting-valve piston G forcing a column of water ten or fifteen feet-'above it, nml the water thus raised forty feet or more.

What I olnim as my invention, end desire to secure by Letters Patent, is-- The arrangement of the slotted tube A, with pointB shrunk upon it, when used in combination with the coupling E, as constructed with valve-box seat, and the pump sections -D D, inthe manner substantially as and i'or the purposes herein fully set forth.
